BROTHER S-7220D-403 NEEDLE FEED (MEDIUM WEIGHT) LOCKSTITCH INDUSTRIAL SEWING MACHINE

The Brother S-7220D-403 is a high-performance single needle needle feed lockstitch machine designed for medium-weight materials, offering exceptional fabric control and stitch precision. It is ideal for challenging applications such as slippery fabrics or multi-layered sewing, ensuring even feeding without shifting or distortion.

This model features a direct drive motor, automatic thread trimmer, and a minimum lubrication system, making it clean, efficient, and reliable for high-volume production. The needle feed mechanism ensures precise fabric movement, reducing puckering and uneven seams, especially for items like polo shirt plackets and layered materials.

With advanced needle breakage prevention, vibration-controlled needle penetration, and IoT compatibility, the S-7220D-403 is built for durability, flexibility, and smart factory integration. A color LCD touchscreen panel with USB support makes operation easy, while the enhanced electronics ensure stability even under voltage fluctuations.
